Bad transaction from a Facebook seller
Not going to go into how to package things anymore. Really sorry this happened to you. The following statement is not aimed at you...
Anybody who puts something in a box without over stuffing the box with packing materials....and then whines about having to deal with a damaged item is a complete effing moron. Anything that goes thru USPS/UPS/FedEx is basicly handled by machinery. Your item WILL NOT be the only one in the shipping container. Your item VERY WELL MAY be at the bottom of it....with upwards of potentially 2000 pounds or so of stuff ON TOP of it. Doesn't take an engineer to figure out what will happen to any open air space.
Guess the idiot that shipped these hasn't ordered anything from Amazon in his life. That or failed to pay attention to the air bags...
